Thoracic Endovascular Aortic Repair after Open Stent Surgery for Aortic Arch and Descending Thoracic Aneurysm: Two Case Reports of Hybrid Treatment

Abstract

Hybrid treatment combined with the elephant trunk procedure and thoracic endovascular aortic repair (TEVAR) for aortic arch and descending thoracic aneurysm have been occasionally reported. In these cases tortuosity of the elephant trunk procedure can cause failure to deploy, difficulty in guiding and migration. We report two cases of hybrid second-stage repair, who underwent TEVAR for descending thoracic aneurysm after open stent surgery for thoracic aortic arch aneurysms. The postoperative courses were uneventful. The stented elephant trunk procedure may be more functional in terms of the landing zone for hybrid TEVAR than the conventional elephant trunk procedure.
